1.向上された臍帯由来付着型幹細胞の製造及び培養方法による比較分析
(1.1)向上された臍帯由来付着型幹細胞の分離及び培養1
正常に分娩した健康な産婦から、事前に十分な説明に基づいた同意(informed consent)を受け、正常胎盤分娩時に収集された胎盤組織から臍帯を分離した。分離された臍帯を、Ca/Mg free DPBSで、2ないし5回洗浄して血液を除去した。その後、外部羊膜は剥がさず、動脈2本及び静脈1本を除去した後、1ないし5mmほどの大きさに臍帯を切った。その後、前記臍帯を培養容器に付着させ、10ないし15日培養を行い、前記培養された組織から細胞が伸び出るところを確認した後、5ないし6時間、200U/mlのコラゲナーゼIを処理し、向上された臍帯由来付着型幹細胞を分離した。前記コラゲナーゼIの処理前、後で臍帯付着した組織から細胞が伸び出るところを確認するために、光学顕微鏡下で、40x,100x倍率で細胞形態を確認し、その結果を図1Aに示した。
前記(1.1)において、コラゲナーゼIの処理を、臍帯を培養容器に付着する前に行ったことのみを除いては、前記(1.1)と同一方法により、向上された臍帯由来付着型幹細胞を分離及び培養した。

前記(1.1)の低酸素条件、及び(1.2)の正常酸素条件において、1ないし20回継代培養(P1ないしP20)された付着型細胞の成長曲線及び倍化時間などを比較するために、それぞれ同数の細胞を6ウェルプレートに接種し、プレート底面積の70〜80%を占めるとき、細胞を収集した。その後、10μlの検体と、トリパンブルー試薬10μlとを混ぜたもの10μlを、血球計算機の一方測定部に注入した。自動細胞計数機を利用して細胞数を測定した。このとき、時間も共に記録し、倍加時間(doubling timeを計算した。該倍化時間は、細胞数が2倍になる時間であり、総細胞数と、それを測定した時間とを利用して計算し、その結果を図2A及び図2Bに示した。
(2.1)向上された臍帯由来付着型幹細胞の遺伝的安定性分析
